This study investigated the influence of obesity on depression and stress by analyzing the results of the national survey on health and nutrition. Relationships between normal, obese, and severely obese groups were investigated. The results of the study are as follows. First, obesity caused by demographic variables showed a relationship to both gender and average monthly income. In the case of the seriously obese group, females had higher rates of depression than males, and the high obesity group had lower average monthly income than the normal and obese groups. Second, obesity caused by health-related variables found that high blood pressure, hyperlipidemia, and diabetes that was not angina-related displayed higher rates of depression in the serious obesity group than in the other groups. As for subjective evaluations of one's own health condition, the serious obesity group showed a high tendency to evaluate their own health conditions negatively. Third, the difference between depression and stress related to obesity level showed no difference between the normal weight group and the obesity group; however, the seriously obese group demonstrated relatively higher occurrences of depression and higher stress scores. Fourth, the result for depression and stress level caused by demographic variables, health-related variables, and obesity demonstrated a direct relationship to gender, subjective level of satisfaction with one's personal finances, average monthly income, subjective perception of one's own health and severely obesity status. More specifically, it was found that the ratio of depression and stress score was higher when the subject was female, among those whose subjective evaluation of their own finances and health condition was negative, and those who suffered from severe obesity.
R$\ddot{o}$hrer index, Vervaeck index and Body Mass Index(BMI) are frequently used in order to judge obese subjects in clothing & textiles field. However, there are no certain criteria of judging the degree of obesity. Each researcher utilized these obesity indices according to their own criteria so far. Therefore, the purpose of the study is to suggest a reliable obesity index and new criteria for judging the degree of obesity. The results are as follows; Utilizing frequency analysis, main percentiles, minimums, maximums and ranges were presented by 5 age groups from twenties to sixties. Obesity rates dramatically increased, the subject got older. Especially, obesity rate of the subjects in their fifties and sixties were much higher than other age groups. 1.6 & higher can be used in the R$\ddot{o}$hrer index, 98 & higher can be used in the Vervaeck index, and 25 & higher can be used in the BMI as the Optimal criteria of the obesity. Total of 24 body measurements and 3 obesity indices were used for analyzing the correlation analysis. All heights measurements showed negative correlation with the 3 obesity indices. It is determined heights measurements have high correlation with R$\ddot{o}$hrer index compare to other indices. Crotch height, interscye back, neck shoulder point to breast point, bust circumference, waist circumference, upper arm circumference and armscye circumference have high positive correlation with all obesity indices. According to the ANOVAs by each percentile group of the R$\ddot{o}$hrer and Vervaeck indices, there are big significances in all measurements and obesity indices except arm length. In general, heights decreased significantly by getting bigger, while circumferences and lengths, widths and indices increased rapidly by getting bigger. The results of the analysis by each percentile group in the BMI, it showed the significant differences in the all measurements except cervical height and arm length. There were similar tendency of differences according to the degree of the obesity in BMI percentile groups. It was confirmed that the BMI is the most reliable index for judging the obesity owing to the high correlations and significant differences with other measurements.
This study was conducted to identify the determinants of regional body fat distribution of obesity(upper body obesity and lower body obesity) for adolescents. The macronutrient consumption pattern utilized the most important variables to test for potential determinants. A total of 726 adolescents living in rural areas in Korea had been observed for four years from 1992 to 1996 about their diet, sexual maturation, serum components and physical growth. The study design was similar to that of a case control study. Logistic regression analysis were used as an analytical method to identify the determinants of upper body obesity and lower body obesity. Odd ratios were estimated from the regression to identify the determinants of upper body obesity and lower body obesity. Odd ratios were estimated from the regression to identify the risk factors. Fat consumption pattern was the most frequent one among the three macronutrient consumption pattern of carbohydrate, fat and protein. Prevalence of obesity for the subjects was 9.5%. Prevalence of upper body obesity was higher in malestudents than in female students. On the other had, prevalence of lower body obesity was higher in females. The results of the logicstic regression analysis showed that the risk factor for upper body obesity was sexual maturity rather than dietary factors. None of the factors included in the analysis for lower body obesity appear to be the risk factor. The result may suggest that to develop a determinant model for obesity of adolescents, the model should include a wider range of variables other than diet, sexual maturity and changes in blood serum.
A counseling manual for the standardized management of obesity in Korean Medicine was developed. Four specialist for obesity and ten advisors participated in the development. The development process was conducted in order to investigate the needs of clinical doctors for obesity, search for related books and references, determine the contents of the manual, produce the manual, and review of the advisors. The contents of the manual were written in order of goal of obesity counseling, assessment of obesity and health risk factors, assessment of obesity-related lifestyles, counseling for weight management, and counseling for Korean Medical treatment. This manual is the first standardized counseling manual developed, and it is meaningful to provide a counseling method for comprehensive Korean Medicine obesity care. Although there were various limitations in the review of the advisory committee, it is expected that this study will be used as a basic data for the establishment of obesity-related health care policy. We hope that obesity counseling of Korean Medicine will be settled as one of the certified korean medical treatment.
Objectives: Despite the considerable interest in the increase in obesity particularly of socially disadvantaged group in Korea, how obesity varies according to various socio-demographic characteristics still remains largely unanswered. To further develop the understanding of obesity in Korea, the present study focuses on the possibility that the relationship between educational attainment and obesity varies across age. Methods: Using 2010 Korea National Health & Nutrition Examination Survey (KNHANES), this study divides the adults into male and female groups and examines the interaction effect of age and educational attainment on obesity through binominal logit models for each group. Results: The most educated male group is more likely to be obese than those who did not complete high school. And the relationship between male's educational attainment and obesity does not significantly change across age. In contrast to male's obesity pattern, female educational attainment has a significant negative association with obesity. The gap in obesity across educational groups converges after middle ages in female. Conclusions: Health policies should pay more attention to those who are more vulnerable to obesity risk in order to effectively reduce obesity.
Object : Waist circumference(WC), waist-hip ratio(WHR), waist-stature ratio(WSR), and body mass index(BMI) are commonly used for evaluating obesity. This Research were done to determine what is more sensitive obesity indexes(WC, WHR, WSR, BMI) Correlated with body composition such as body fat mass, body fat(%), visceral fat area, and fat free mass. And what is more sensitively correlated obesity indexes with % changes of body composition during weight reduction treatment. Methods : This clinical retrospective research were carried out 127 cases of female obese outpatients with weight reduction treatment during 1 month. Bioelectrical impedence analysis(for body composition) and body size(for anthropometric obesity indexes) were estimated in pre-treatment and post-treatment to evaluate the obesity indexes. Pearson correlation coefficients were used to select useful obesity index. Result & Conclusion : BMI is useful index for diagnosis and evaluation of obesity. WSR is sensitively correlated with visceral fat area and body fat(%). So, WSR is useful index for evaluating abdominal obesity and risk factors of metabolic syndrome. WC is correlated with both body fat mass and fat free mass. WHR is not optimal for diagnosis and evaluation of obesity.
Excessive body weight gain during the growth period of early life may predispose individuals towards obesity and metabolic disorder in later life. We investigated the possibility of using the food efficiency ratio as an early indicator for predicting susceptibility to diet-induced obesity and insulin resistance. Four-week-old, prepubertal, male Sprague Dawley rats were divided into obesity-prone and obesity-resistant groups based on food efficiency ratio values after five days on a high-fat diet. Metabolic parameters measured after 2, 6, and 10 weeks, and specific phenotypes were compared with each group. Obesity-prone rats had higher increases in body weight and fat mass compared to obesity-resistant rats over the study period. Obesity-prone rats became glucose intolerant early in this study and remained so throughout the experimental period, with increases in fat weight and leptin levels occurring first, followed by increases in insulin level. Gluconeogenesis and insulin resistance significantly increased in obesity-prone groups in which activities of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase were increased and glucokinase activity decreased. Higher food efficiency ratio at an early age was closely correlated with body fat accumulation, hyperleptinemia, and hyperinsulinemia of middle and elderly age. We suggest a high food efficiency ratio in prepubertal subjects may be a useful predictor of future obesity and insulin resistance.
Objectives: The purpose of this study was to review predictive factors associated with weight loss in moderate to severe obesity treatment. The direction of the treatment for moderate to severe obesity will be suggested in consideration of various factors. Methods: Authors searched the articles published from 2018 to 2023 in three international databases (PubMed, Embase and the Cochrane Central Register of Controlled Trials) and two domestic databases (Research Information Sharing Service, Korean studies Information Service System). Studies including treatment with moderate to severe obese patients were selected. Results: A total of 43 studies were included. The main factors of weight loss were unchangeable predictors such as low initial degree of obesity, younger age, non-diabetes and high resting energy expenditure with changeable predictors such as increase in protein, physical activity, self-efficacy, initial weight loss and attendance of the treatment. Conclusions: Our review results suggest that based on the characteristics of moderate to severe obese patients, predictors of weight loss can be used to determine treatment and prognosis in various aspects.
Objectives: The objective of this study was held for prevention of coronary artery disease and improvement of health of local community residents by classifying the obesity types of their waist circumference and BMI, and appraising the coronary artery disease risk factors(CRF). Methods: We analyzed the data on the 1,914 adult cases (1,156 male and 758 female) during Nov, 2006 to Mar. 2007 on a general hospital in Daegu city, Korea. The obesity types in this research were classified into normal group, seeming obesity group, abdominal obesity group and obesity group. Also, CRF was classified by normal, mild, moderate, and severe, and each class was given the index from 0 to 3. The coronary artery disease risk factors index(CRFI) was defined as the sum of index, and we defined that if the sum is higher, higher chance of coronary artery disease risk exist. Results: According to the research, by the age group, normal group has higher percentage in age 30 to 40, and obesity group and abdominal obesity group has higher percentage in age 50 to 60. CRFI is increased by order of normal group, seeming obesity group, abdominal obesity group, and obesity group on both male and female groups, and male shows higher index than female on all four groups. CRFI will be influenced by order of obesity group, seeming obesity group, and abdominal obesity group on male, and obesity group, abdominal obesity group, and seeming obesity group on female according to the result of multiple regression between obesity type and CRFI. Conclusion: According to the result from our research, we have to have keen attention to not only seeming obesity group and obesity group, but also abdominal obesity group which has normal waist circumference influence to CRFI. So, those kinds of indexes have to be controled by controling their weight. Also, we believe that health behaviour can improve and CRF can be prevented by the early health care and early health education to those with no abnormal indication on clinical indicator but with abnormal BMI and waist circumference.
This study was intended to provide basic data of nutrition education to a prevention of obesity and living patterns of elementary school students. Through the measurment of the actual obesity rate of children for students who were in the fifth and sixth grades of elementary school as well as their mothers, and by analyzing obesity-related factors. Children have started to have the characteristics obesity and obesity problems. 1. There were total 234 children including 133 boys (56.8%) and 101 girls (43.2%) for the study. There were 80 children in the fifth grade (34.2%) and 154 children in the sixth grade (65.8%). 2. Among the subjects 20.1% were obese. By gender, the obesity rate of boys (27.1%) was higher than that of girls (l0.9%)(p<0.01). By grade, children in the fifth grade (26.3%) had higher obesity rate than children in the sixth grade (l6.9%)(p<0.05). 3. In terms of the educational level of parents, the obesity rate of children of parents who received university and/or higher education was 27.5% (p<0.05). 44.1% of parents answered ‘I almost never give snack’s’(p<0.01). 4. There was 32.8% for an irregular quantity of meal. There was no obese child who under-ate (p<0.05). In terms of impulse eating, ‘I eat.’ and ‘I don't eat.’ were 24.4% and 25.9% respectively. The obesity rate of the case of ‘I eat only food I like.’ was 10.6% (p<0.05). In terms of the obesity rate based on the daily average meal frequency, there was the highest rate of 26.1% for I average meal frequency per day, 13.0% for 2 daily average meal frequency, and 7.4% for over 3 average meal frequency per day (p<0.05). For a degree of a physical activity, the group of active physical activity (p<0.05) and the group which liked the physical exercise showed a lower obesity rate (p<0.001). The obesity rate of children who had regular exercise was 11.8%. It was lower than the obesity rate (24.8%) of children who didn't exercise (p<0.01). The higher exercise frequency per week was, the lower the obesity rate was(p<0.01). In terms of the exercise time, there was 8.3% for over 60 minutes and 28.9% for less 15 minutes. The group which had the long exercise time showed a lower obesity rate(p<0.05). As the result, the education for obesity must enable students to recognize the warning signs for obesity and control their own weight with proper living patterns, by modifying behaviors considering the degree of obesity. Obesity must be controlled by the prevention and education connected with the family for all students as one of the school health programs. There must be also the development of a program through individual consultation considering the degree of obesity.
